I re-ran the numbers on 10GE against the actual alacrityvm v0.1 release
available in git on kernel.org.
I tried to include the newly announced "vhost" driver (Michael Tsirkin)
for virtio acceleration, but ran into issues getting the patches to apply.
For now, this includes native, virtio-u (virtio-userspace), and venet
all running on 31-rc4. If I can resolve the issue with Michaels
patches, I will add "virtio-k" (virtio-kernel) to the mix as well. For
now, here are the results for 1500mtu:
native: 7388Mb/s, 29.8us rtt (33505 tps udp-rr)
venet: 3654Mb/s, 56.8us rtt (17600 tps udp-rr)
virtio-u: 1955Mb/s, 4016.0us rtt ( 249 tps udp-rr)
Just FYI, the numbers quoted are wrong for virtio-u. Greg's machine
didn't have high res timers enabled in the kernel. He'll post newer
numbers later but they're much better than these (venet is still ahead
though).
